Sounds like you might be having the infamous lookupd problem:
http://www.stepwise.com/Articles/Technical/Lookupd.html
Mine just showed up one day also and proceeds to make my life miserable. I
experience the exact same symptoms as you describe. Once a month or so I
get up at 3:00 am, drive to the server room and restart the system. You
can't telnet in to reboot because all lookup services (including login and
password) are dead. The bug is apparently involves some algorithm related
to certain IP address structures. Something like subtract your birthdate,
add the number of molecules in a strawberry and divide by the population of
Taiwan. There's no fix and I can't leave OSX 1.2 until I get all of my
WebObjects applications converted to 5.0.
